RAILWAY BOX FREIGHT CAR.

Application tiled January 8, 1927. Serial No. 159,962.

My invention embraces the construction of steel railway box car bodies having steel floors and self-supporting sides, all preferably of pressed forms of corrugated steel which en- 'tirely eliminates the usual side sills, and the usual side framework consisting of steel struts and braces and the use of lumber; with the object of simplifying the construction of said cars and of materially reducing the number of parts and the amount of labor involved in their manufacture.

In the accompanying drawing Figure 1 is an outlineside elevation of the box car. Figure 2, on a larger scale, a half section transverse elevation at A--A, and a half section through the side at B-B in Figure 1. Figure 3, a sectional plan of the preferred construction of the corner joinin the sides and ends and Figure 4, a section 0 a fragment of the ooring.'

- The side sheets, 1, are designed to be of pressed steel, girdershaped, moulded from sheets of the largest commercial sizes which ma be convenient, riveted together and of su cient thickness to be self supporting without the usual side sills, and referably of corrugated form. The ed es 0 these side sheets ma be strengthened y flanges, 2, at the top e ge and, 3, at the bottom, and may be further re-enforced by strips, 4, at the top and, 5, at the bottom to increase the strengt of the girder form of side, particularly'under the doorway. Thewords, self-supporting, a plied above to the side sheets, mean to 38 inclu e the proportion of the lading usually upheld by the slde sills.

e floor, 6, is also composed of sheet metal plates, preferably of corrugated form, as

dicated in Figure 4, suitably flanged to enable them to be riveted to each other and to the side and end sheets. The corrugations may be filled with cement if necessary to ma e a smooth floor.

. The doorways, 7, are flanged, at 8, all around, preferably inwardly as shown. Transverse braces, 9, are applied from doorway to doorway at the top,.attached firmly to the flanges, 8, to prevent excessive torsion sides constructed of self-supporting metal sheets-which form a continuous girder from end to end, substantially as described.

4. A railway box freight car having its flooring constructed of corrugated sheets of metal transversely disposed, substantially as described.

5. A railway box frei ht carhaving its sides constructed of selisupporting metal sheets and having flan ed doorways cut therein substantially as described.
